Further, Amora Gem is also able to match the world's most valuable white diamonds in color and clarity, with up to D color, and Internally Flawless clarity.

The Amora Gem is over one million times rarer than diamond (based on the past 10 years of natural diamond production vs Amora Gem production).

Amora Gem is composed of 50% carbon and 50% silicon, and only grows in star-like conditions that would vaporize diamond.

The Amora Gem crystal naturally occurs around large stars as stardust, but was never available on Earth until now (thanks to seven figures and eight years of research and development).

Amora Gem is grown in a laboratory where the star-like conditions it naturally grows in have finally been replicated on Earth. Thus every Amora Gem is 100% conflict-free and environmentally friendly.

Amoras are each individually graded under the GIA diamond grading scale and priced according to their carat weight, color and clarity.

We do the initial cutting our Amora Gems with our own in-house built TIGER robot system. With <10 micron precision, it is the world's most advanced gem cutting robot. Our TIGER robot is now multi-patent-pending!

(In addition, our robotic cutting facility is now 100% green energy powered from a mixture of primarily wind, but also solar/low impact hydro).

The Eternity H&A thus delivers incredible H&A symmetry and precision including our synchronized 64 facet, vertical faceted girdle so you can enjoy the world's most stunning and most perfectly cut gem, Amora!

Below: a Sarin HD Analysis of a common, mediocre diamond, an H&A diamond and an Amora Gem proving the cutting precision of the Amora Gems. Sarin HD is the only 3D scanner approved by GIA for symmetry grading as it does a facet by facet analysis with extreme precision. (Explanation = "Dev" is "Deviations from perfect" where smaller is closer to perfection. 0.0 would be absolute perfection. You can see the march towards perfection from Diamond->H&A Diamond->Amora Gem).

Note that the 64 facet girdle is a time consuming endeavor - this is why it's only done on high end gems like the Amora Eternity H&A, and H&A mined diamonds.

CZ, Moissanite, etc. all go the generic "polished" girdle which is quick and easy to do - just polish around the girdle and done. For Forever One Moissanite, the girdle is only 95% polished - the area they will laser engrave is left rough.

Above: Forever One Moissanite girdle photo - polished girdle only, no faceting. Amora Eternity H&A is the only diamond alternative with a 64 faceted girdle, same as H&A diamonds.

Note that the polished girdle (unfaceted) makes it quick and easy for anyone to simply look at a gem from the side and immediately tell if it's a low value CZ or Moissanite, or a high value H&A diamond or Amora gem. The girdle is extremely telling in that respect, which is why Amora Gem is unique in the diamond alternative market for perfecting every aspect of our Eternity H&A, including a high end 64 facet girdle.

Eternity H&A Cut design - Cut controls 98% of the brilliance:

Our new Eternity H&A Round is the result of using the world's most advanced gem modeling software (currently owned only by the GIA and BetterThanDiamond in the US), and then a month of deep computing simulations using the only stereoscopic modeling system in the world, along with ten years of real-world evaluation of thousands of H&A diamonds (credit to Jonathan Weingarten, AugustVintage.com).

Stereoscopic modeling mimics exactly how you see - which is in fact a slightly shifted left image (left eye), and a slightly shifted right image (right eye) with the final "picture" of a stone being the combination of these images in your brain. Thus, what looks good under standard monoscopic modeling is really only applicable for a cyclops, rather than dual vision humans. As a result, the Eternity H&A was developed and perfected as the ultimate in Fire and Brilliance for the Amora Gem based on stereoscopic human perception. The result is the most firey and brilliant Amora Gem in real life viewing!

The Eternity H&A is the successor to our previous Soaring Hearts & Ultra H&A cut. Note the difference in the Eternity H&A arrows, which are now an optimal medium thickness:

Amora Gem is the world's newest gem, a cousin to diamond, and the most brilliant member of the 200+ member silicon carbide family. While diamond is composed of 100% carbon, Amora Gem is 50% carbon and 50% silicon.

For the first time ever in human history, Amora is now available as a gem on our planet. While diamond has previously been the most desirable gem, the Amora surpasses diamond in every aspect of optical beauty and toughness.

Yes. While Amora Gem for jewelry use on Earth is grown in a laboratory (and thus avoiding the issues related to mining), it is a naturally occuring crystal that has existed as stardust around large carbon-rich stars for eons, long before our planet was born (see Astronomy & Astrophysics journal, April 1988). The starlight you see in the night sky may very well have sparkled off Amora gem stardust.

Since Amora Gem only grows in conditions that would vaporize diamond — extremely high temperatures such as those around larger stars — it is not naturally found on the Earth like diamond is.

It is only now after eight-plus years of research and development that the star-like conditions required to grow the Amora Gem crystal have been achieved in a lab.

Thus, for the first time in 4.5 billion years since our Earth was formed, Amora Gem is finally available here on Earth to jewelry lovers around the world in very limited quantities.

When were the first Amoras shown and sold?

The first sales of Amora Gem started in July 2013, right here on our website since we are the official maker of this stunning gem. One of the very first Amora Gems was displayed at the Hungarian Natural History Museum as the newest/youngest crystal on our planet. The first larger Amora Gem now graces the finger of a former Miss America.

Why was Amora Gem crystal never available on Earth until now?

Due to the incredibly high temperatures Amora Gem requires for growth - literally star-like conditions, it has never been available as a gem crystal until now. Its lack of availability is perhaps one reason that diamond became the most prized gem on Earth.

The multi-patent-pending Amora H&A lab-grown gem is now available to consumers in select countries for the first time.

Just like most higher-end diamonds, every Amora Gem comes with its own independent grading report, performed under GIA Diamond grading standards, to advise you of the essential parameters of your own Amora Eternity H&A:

Amora Gem competes with diamond on the basis of its intrinsic properties and beauty — greater fire, greater brilliance, greater luster, greater toughness and 100% conflict-free and environmentally friendly. However, cost is a fifth C beyond Color, Clarity, Carat and Cut, which is certainly another bonus for the Amora Gem Eternity H&A.

Below is a price comparison of various natural H&A diamonds versus Amora Gems, taken from BlueNile.com on May 15, 2014. Note that H&A becomes extremely rare in natural diamonds over 3ct size, so Ideal cuts had to be used after that. You can see the distinct pricing advantage of the Amora Gem when you make exact apples to apples comparisons of color, clarity, carat size and cut. (Note: You may click on the diamond price to jump to the diamond in question to see the details, provided the diamond has not already sold).

We will set the Amora Gem into your desired ring so you receve a finished, ready-to-wear ring. We split the ordering process into two so you may order the exact Amora Gem you wish for your ring.

What is the most popular ring for Amora Gem Eternity H&A? By far and away the most popular ring customers pick to hold their Eternity is our Timeless Regal ring (which also happens to be our single best-selling ring overall). Details for this ring are here.

Amora H&A lab-grown gem compared to diamond:

More brilliant than diamond

More fire than diamond

Greater physical stability and tougher than diamond

D, E and F color — better color than most diamonds

Hearts and arrows precision — better cutting than 99% of all round diamonds

Much, much rarer than diamond. Amora Gem previously only existed around large carbon-rich stars, unavailable to any humans on Earth for over four billion years of Earth's history. Now that Amora is grown in a lab by creating star-like conditions, the total production is a small fraction of the annual mining output of natural diamonds.

Amora Ultra H&A is The Ultimate Gem.

Multi-patent pending, and Patented: Amora Gem is now Multi-Patent Pending in the US, and we have additional foreign patents in progress in China, Canada, India, etc. (US Patent applications include: 13224468, 13733061 and 14020639, and International patent application: PCT/US12/28892). Patented - Australia, 2016100041.

Eternity Hearts & Arrows™ :

Within a given crystal type, cutting controls 98% of the brilliance. Hearts and arrows cutting is the absolute premiere cut for natural diamond, but only 2% or less of natural diamonds are ever cut to this level of optical perfection. Because Amora has much greater brilliance and fire than diamond, the hearts and arrows parameters had to be completely revised and improved for the Amora Gem to account for its superior optics.

In an industry first, all Amora Eternity H&As are cut *exclusively* by robot. Robotic cutting enables super-human precision and incredible craftsmanship compared to hand cutting, ensuring that the Amora Eternity H&A has unparalleled precision and beauty.

Amora H&A gem compared to other gems:

More brilliant than moissanite (Amora GEM is a different crystal with superior optical properties than moissanite). Amora Gem is the most brilliant gem anywhere.

27% harder than sapphire

More brilliant than cubic zirconia

Harder than cubic zirconia

In short, Amora gem is truly the ultimate gem, eclipsing diamond in every measure of optical beauty.

Availability :

Amora Eternity H&A is currently available for sale, but due to high demand and low supply, some sizes are periodically sold out. We are working hard to increase our total production by increasing the number of cutting robots this year.

Note: Currently our Asha H&A round is the best proxy for now if you are waiting for the Amora H&A Gem, as it has similar depth measurements.

I am from the Philippines and I had it shipped to my friend working in Singapore to take advantage of Singapore's reasonable customs tax. And when she gave it to me, we were in a restaurant with a very good lighting. It was really stunning!! You can really spot the ring from across the room with that spark! I observed it in different lighting condition, like indoors, at night, under sunlight and it performs really well in all those. My original plan was to get something from bluenile, but I'd be spending more than 20K USD on a diamond with a spec like this!
Kudos to their customer service, they made my ring arrive to Singapore before my friend's flight to the Philippines. Expect transactions from me in the future! And probably more transactions from the Philippines!
